This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X15SFB, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.

The AirTAC Airtac SU32~50 Standard Cylinder SU32X15SFB is a double-acting profile-type standard cylinder with a Ø32mm bore and 15mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X15SFB, which matches its bore, stroke, force and mounting.
The AirTAC SU32X15SFB is a discontinued double-acting profile-type cylinder with a 32 mm bore and 15 mm stroke. Built with an extruded aluminum barrel and adjustable air cushions at both ends, it delivers 402 N of push force at 0.5 MPa. Because this SU model is end-of-life, AirTAC supplies the SAU32X15SFB as the direct replacement: it matches the 32 mm bore, 15 mm stroke, 1/8" port, M10x1.25 rod thread and SC-series FB mounting interface exactly.
This compact profile body is shorter than an ISO 15552 cylinder of the same bore. The -S magnet on this legacy unit works with CS1-B/DS1-B switches, but the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X15SFB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X15SFB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Ideal for compact 32 mm bore clamping jigs where a brief 15 mm stroke securely holds lightweight machining components without consuming excessive tool space.
Provides rapid part ejection in small assembly cells, leveraging the 402 N push force at 0.5 MPa to clear finished goods from tight fixtures quickly.
Suitable for actuating small pneumatic diverter gates on conveyor lines, where the compact profile body and FB mount fit neatly within restricted frame clearances.
To replace the SU32X15SFB, order the SAU32X15SFB. Verify your 1/8" port thread (PT, G or NPT) and confirm the FB mounting bracket is reused. Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU replacement. If you need to upsize, the adjacent 40 mm bore yields 628 N push at 0.5 MPa; downsizing is not recommended for this smallest standard profile bore. A plain cylinder does not hold load without live air—the cushion only decelerates—so for vertical holding add an external rod lock or pilot-operated check valve. The 15 mm stroke is very short, so side-load risks are minimal, but always guide the load to prevent rod bending.
Replacement checklist
Yes, the SU32X15SFB is discontinued. The direct replacement is the AirTAC SAU32X15SFB. It shares the same 32 mm bore, 15 mm stroke, output force, 1/8" port, and SC-series FB mounting, so it drops directly into the same application.
At 0.5 MPa it provides 402 N push and 345 N pull force, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The -S magnet on this unit works with legacy CS1-B/DS1-B switches; the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X15SFB replacement — usually within 7-8 hours.
